Summary

Completed in 2009, this reservoir has a hydraulic height of 22 feet and a structural height of 19 feet, with a storage capacity of 36 acre-feet. The reservoir covers a surface area of 2.3 acres and serves the local community by providing water for agricultural irrigation.

Managed by the Washington Department of Ecology, Selah Home Ranch Reservoir is regulated and inspected regularly to ensure its safety and functionality. With a high hazard potential but a satisfactory condition assessment as of October 2019, the reservoir is equipped with emergency action plans and meets guidelines for risk management. Its location in the Yakima County provides vital water resources for the surrounding area, contributing to sustainable agriculture and climate resilience efforts in the region.

Not only does Selah Home Ranch Reservoir play a crucial role in supporting agricultural activities in the area, but it also serves as a valuable asset for water resource management and climate adaptation. With a maximum storage capacity of 36 acre-feet and a drainage area of 0.24 square miles, this reservoir plays a vital role in ensuring water security for the local community. As climate change continues to impact water availability and irrigation needs, Selah Home Ranch Reservoir stands as a key infrastructure for sustainable water management in the region.

Condition Assessment

Satisfactory
No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.

Hazard Potential Classification

High
Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
